Intramolecular alkyl ligand transfer in dinuclear complexes

5 Intramolecular alkyl ligand transfer in dinuclear complexes 

Similar reactions of Pt-Mo and Pt-Fe complexes also cause alkyl ligand transfer induced thermally or by addition of rt-acid that enhances activation of the metal-carbon bond [216-218]. The reaction of Pd-Co complexes containing Pd-Me bond with CO leads to formal insertion of CO into the Pd-Me bond (Eq. 5.70) 

The formation of the dinuclear complex with a bridging alkynyl ligand and its rapid switching from the to the coordination mode provides 

Reversible transfer of the alkyl group between the metal centers has been observed in dinuclear Rh complexes (Eq. 5.72) [222]. 

The above intramolecular reactions involve dinuclear intermediate with a symmetrically bridging alkyl, aryl, and alkynyl ligands.
